Field notes
The designer divides each coupling into a left end, a connecting neck, and a right end; users can set thread standards, socket depth, neck length, diameter, and bore. The page describes solid, watertight ASCII STL exports and gives print guidance, including 0.12–0.16 mm layers, five or more walls, and full infill. It cautions against relying on home-printed parts where a leak could cause damage.
